Transport Stream Properties
Mux Parameters
| Parameter name | Description | Possible values |
|---|---|---|
| Total Bitrate* | Dimensions the bandwidth at multiplexer output. Embeds PSI and NULL bit rates, as well as the sum of the video/ audio/private stream bit rates embedded in multiplexer output. | 0 to 200000000 bps |
| Minimum Null Bitrate* | Reserves NULL packet bandwidth. If component bitrate + null bitrate > total bitrate then component packets will be discarded | 0 to 200000000 bps |
| Transport Stream ID* | Sets the Transport Stream ID in the output PAT, SDT and NIT (if enabled) | 0 to 65535 |
| Original Network ID* | Sets the Original Network ID in the output SDT and NIT (if enabled) | 0 to 65535 |
| Source Redundancy Mode | See redundancy mode paragraph. | Dropdown menu: Automatic no monitoring, Manual no monitoring, Automatic with monitoring, Manual with monitoring. |
| IP Active/Standby | Enable Active/Standby for IP output | Tick box, disabled by default |
| Scramble transport stream packets containing a PES header | TS packets containing a PES header are scrambled if scrambling is required for the current service. | Tick box, enabled by default |
Mux Advanced Settings
These settings are only for advanced configurations. Default values should be suitable for the majority of use cases.
| Parameter name | Description | Possible values |
|---|---|---|
| Input jitter buffer latency | The latency on each input used to absorb input jitter. Requires a service restart to apply. Reducing this value can reduce the latency of the service in the multiplexing stage. However, depending on the service configuration (FEC and or RTP enabled) and on the input bitrate, reducing this value could lead to insufficient buffering available for the muxing process. In such case, an alarm will be raised to notify about possible problems in the output stream. | 10 to 30000 ms |
| Scrambling latency | The added latency during which scrambling occurs. | 10 to 30000 ms |
| ASI Active/Standby | Whether ASI outputs should stop when in standby or not. | Tick box |
| Copy SDT as SDT Other | Controls which other transport streams will receive a copy of the SDT | Dropdown menu: To all networks, To same network, Do not copy |
| Hide transport stream | Hide this transport stream in the NIT included in other transport streams of the same DVB network | Tick box |
| ASI output buffer latency | The output latency added when using ASI. Applies only to DekTec cards. | 10 to 30000 ms |
| IP output buffer latency | The IP output latency. | 10 to 30000 ms |
